(01.206-165) This invention relatesgto improvements in a receptacle for clinical thermometer, and has'for its ofject to provide a means for rotation of itself in order to have the mercury in the column 5 return tothe bulb by centrifugal force.

The drawing illustrates the receptacle of this invention, in which Fig. 1 is a perspective viewof the same, and Fig. 2 is a sectional plan thereof.

In th'edrawing, 1 is a-clip attached to an upper part of the receptacle 4 which consists of a long cylindrical body and, a cylindrical cap therefor. The clip is made of metal strip curved in 0 form so as to firmly catch the circumference of the receptacle by its spring action. It has an armor extension 1a which ,co-operates with the wall of the receptacle in order to clamp the latter to the brim of a pocket or the like.

The clip has two perforations 2 on its opposite sides leaving a bridged portion 3 between them as shown in the drawing. The bridged portion 3 is expanded outwards so that a small passage is left between the portion and the surface of the receptacle. Through these small passages is" extendeda string 5 and its ends are tied together. When the mercury column of a clinical thermometer has risen, and the" mercury is to be returned to the bulb, the thermometer, according to this invention, is put in the receptacle as usual, and after the cap is fitted one is to pickup each end of the string 5, and the receptacle should be rotated on the string so as to twist the string on each side of the receptacle. When the string has been fullyctwisted, it should be stretched by pulling the ends of the string outwards so that the receptacle is rotated in an opposite directionum" twisting the string, and then the string is further twisted in that direction by inertia till the string -is fully twisted again. This action is repeated a few times, then the mercury column in the thermometer will be returned to the bulb due to centrifugal force produced by the rotation.

In order to return mercury in the'column to the bulb of a clinical thermometer, the

latter is generally swung by a hand. This not' I only requires considerable troublesome work but 7 also the thermometer may sometimes fly off'from'. the hand. According to my invention, the receptacle can be rotated very easily, and the cost of the clip'is not expensive.

What I claim is: i I A restoring device, for clinical thermometer receptacle comprising a clip secured to, the upper ,75

part of the receptacle, which clip consists of a metal strip of c section'with an extended arm keeping a narrow clearance along the surface of the receptacle, and two perforations are provided on the opposite sides of the clip leaving abridged 30 portion between the perforations, which portion is expanded outwardly so as to form a small passage between the bridged portion and the surface of the receptacle, and a string inserted throughthe passages, adaptable for handling of the receptacle. 1 c
